Verdict
The clearest difference is review sentiment: EE ToolKit at 90% against Engineering & FE Prep's 62%. EE ToolKit also leads on rating (4.7 vs 4.5) and ratings volume (1.4K vs 171). Engineering & FE Prep's advantage is update cadence (every 2 weeks vs every 3 months). On price, ads, in-app purchases and monetization model there is nothing between them.
